Hi,
Some of the very technology savvy people on list will have realized that Apple has posted the next major revision to Quicktime (QT), now at version 7.0.
There seems to be consensus on the web regarding four accepts of the QT: 1. The video quality to absolutely phenomenal - High Definition video over the web ... who would thought it possible so soon.

2. If you purchased the upgrade to QT Pro 6.0, your release key will not work to enable the pro functionality in QT 7.0. However, the upgrade price has not changed from version 6.0. Please bear this in mind if you are running FinalCut Pro in a production environment, as you might inadvertently disable your workstation until you pay to obtain the QT 7-Pro upgrade.
3. QT 7 includes the new video codec H.264. Okay so you're thinking "what does that mean" ... see point (1) above. This kind of modern mathematical compression technique requires significant CPU power to drive H.264 video at full frame rate (24 frames/sec). Specifically a high speed G4, 1.5GHz or better to see full frame rate.
4. For content creators H.264 also requires significant CPU power to encode video in H.264 (e.g. G5 processor).
That said, QT 7.0 looks to be a excellent product for video professionals and regular users of video content. However, you might want to pause for a second a review your use of QT and how the new version will run on your equipment BEFORE downloading the update.
